MU Calculations and the GS-8800 Conformance System

Application Notes

Introduction

When measurements are performed there are unavoidable factors that can vary the result. Though often minuscule, these variances are referred to as measurement uncertainty (MU) and they are inherent in every measurement. 

For a conformance test system, it is a requirement that the system MU be taken into account based on the standard MU guidelines: the “Guide to the Expression of Uncertainty in Measurement” (GUM) (1995). The Keysight Technologies, Inc. GS-8800 conformance test system is designed in accordance to this MU standard as required by regulatory and accreditation bodies. This adherence ensures that a level of system measurement repeatability and reproducibility is achieved and meets the ISO 17025 standard. This application note explains how MU affects GS-8800 system measurements and demonstrates how MU is derived for the conformance test system.
